Correct and also STRONGLY not recommended, actually, at gun point not recommended to use JB4+ Flash Tune.

Once I am comfortable with the flash tune, I'm going to do some logs with the JB4 and get it re-enabled to just control the meth injection. Hopefully by then there are more options for a transmission flash.

I had a jb+ for some time with a bms intake, not bad for the money but car was still sluggish when shifting, felt as if the car was having a meeting with GMBH whenever I shifted and they delayed the decision to reaccelerate.

Not anymore, enter JR, punches GMBH in the head, bangs everyone's wife and sprinkles magic on the ecu

I would like to share my experience for MG Flasher with an EU-car with MPPSK.
3 weeks ago I flashed stage 1 (ron98) in beta phase, I had some issues saying 'license not available' on my mobile but Jarek was quick and solved remotely. The car feels very powerful, power delivery is really smooth, gauges show corrected numbers in KW and NM, Jarek is doing a great Job!

@Jarek: My greates wish is a map such as stage 2 that cuts torque to ~550NM in the midrange to prevent torque intervention but powers up to ~440hp. Do you have any plans on that?
